AB  - Moniliformin (MON) represents one of the most widespread emerging mycotoxins, whose presence in food and feed can potentially cause harmful effects on the health of both the public and animals. In order to investigate MON occurrence, a total of four hundred (n = 400) samples of unprocessed maize were sampled from different regions (Bačka, Banat, and Srem) of Serbia during a period of four years (2018–2021) and were analyzed using a validated liquid chromatography with tandem mass spectrometry (LC-MS/MS) method. The influence of regional differences and variations from year to year in terms of weather conditions on the occurrence of MON was also assessed. The obtained validation parameters indicated that the LC-MS/MS method is applicable to the determination of MON in maize samples. It can be observed from the acquired findings that all samples were contaminated with MON, while concentration levels varied between the samples, especially from different sampling years. The maize samples showed the greatest levels of MON concentration during the dry and hot climatic conditions experienced in 2021. In maize samples harvested in the period 2018–2020, the MON concentration levels detected were about two to three times lower compared to the year 2021. Additionally, a comprehensive investigation into the correlation between weather conditions and the occurrence of MON in maize grown in Serbia was undertaken by reviewing the outcomes of research undertaken in the past decade.

AB  - In this work, a simple and rapid electrochemical method is presented for the voltammetric determination of histamine based on carbon paste electrodes bulk-modified with single-walled carbon nanotubes. As monitored in cyclic voltammetry histamine undergoes an irreversible electrochemical oxidation with a peak potential of ca. +1.25 V (vs. Ag/AgCl, 3 mol L-1 KCl) in phosphate buffer solution (PBS, 0.1 mol L-1, pH 6.0). At optimized differential pulse voltammetric parameters, the current response of histamine was linearly proportional to its concentration in the range from 4.5 to 720 mu mol L-1. A low limit of detection of 1.26 mu mol L-1 and a limit of quantification of 3.78 mu mol L-1 of histamine, as well as good reproducibility (RSD = 0.48-3.40 %) were obtained using the carbon paste electrode modified with single-walled carbon nanotubes. The proposed sensor was successfully applied to the determination of histamine in commercial beer and wine samples.

AB  - This study examines the mineral composition of the extracts of the fruits, leaves and roots of white mulberry (Morus alba L.) and black mulberry (Morus nigra L.) grown in Serbia. All extract samples of white and black mulberry were analyzed for the content of micro (B, Co, Cr, Cu, Fe, Li, Mn, Ni, Se, Sr, Zn), macro (Ca, Mg, Na), and toxic metals (Al, As, Cd, Hg, Pb) by inductively coupled plasma optical emission spectrometry (ICP-OES). The study revealed that parts of the plant had statistically significant impact on the levels of the examined elements among the two Morus species. All extracts contained high amounts of Ca, Mg, Na, B, Cu, Fe, Mn and Zn. The studies showed that in the most of extracts dominant macro element was Mg (591- 1942 μg/g of dry extract), while dominant microelements were Zn, B, Cu in all extracts, except for the black mulberry leaves, whose extract was most abundant in Fe (143 μg/g of dry extract). The highest content of micro and macro elements was detected in the extract of black mulberry leaves. This work contributes to the knowledge of the nutritional properties of Morus species. The obtained results may be useful in the evaluation of new dietary and food products.

Ispitivanje je pokazalo da postoji statistički značajna korelacija između delova biljke Morus vrste i sadržaja ispitivanih elemenata. U svim ekstraktima je dokazan visok sadržaj elemenata: Ca, Mg, Na, B, Cu, Fe, Mn i Zn, respektivno. Dominantan makro element u većem broju ekstrakata je Mg (591 - 1942 μg/g suvog ekstrakta). Što se tiče mikroelemenata, u svim ispitivanim ekstraktima u većem sadržaju su zastupljeni Zn, B i Cu. U uzorku M. nigra posebno se izdvaja Fe po svom sadržaju (143 μg/g suvog ekstrakta) u odnosu na ostale prisutne elemente. Od svih ispitivanih uzoraka najviši sadržaj mikro i makro elemenata je detektovan u ekstraktima lista M. Nigra. Ovaj rad doprinosi poznavanju nutritivnih svojstava Morus vrsta. Dobijeni rezultati mogu biti korisni u kreiranju novih dijetetskih i prehrambenih proizvoda.
